SELF-CLEANING'CUSPIDOR.

SPECIFICATION forming part of Letters Patent 0. 651,475, dated June 12, 1900. Application filed March 26, 1900. Serial No. 10,235. (No model.)

T0 to whom it may concern:

Be it known that I, ELIE BENOIT, a citizen of the United States, residing at Worcester, in the county of WVorcester and State of Massachusetts, have invented certain new and useful Improvements in Self-Cleaning Cuspidors, of which the following is a specification.

My invention relates to self-cleaning cuspidors, and more particularly to an improved construction of the cuspidor shown in my United States Letters Patent No. 570,217.

The object of my present invention is to simplify and cheapen the construction of the valve mechanism and to provide for the flow of water into the ouspidor, if desired, without discharging the contents thereof, as will be hereinafter described.

Referring to the drawings, Figure 1 is a plan view of a cuspidor embodying my improvements. Fig. 2 is a central vertical section on line 2 2, Fig. 1, looking in the direction of the arrow, same figure.

In the accompanying drawings, 1 is the cuspidor, of basin shape, intended to be set into the floor, so that its top surface will be flush with the floor and secured thereto by screws 2, as shown, or otherwise.

The cuspidor 1 has a removable perforated top 3, which is made with openings therein, preferably as shown, and is held in place in any suitable way, as by a pin 3, extending into a slot or opening in the inwardly-extending flange 1 on the cuspidor 1, as shown .in Fig. 2. I

The cuspidor 1 has an outlet or discharge a through its bottom, an overflow Z) on one side, and an inlet 0 on one side, through which inlet the water flows into the cuspidor.

I will now describe my valve mechanism, to which my present improvements more particularly relate. The cylindrical valve shell or casing 4 is fast in the inlet-opening o in the cuspidor 1. Within the casing 4 is a springactuated valve 5, having the taper portion 5' to fit in the taper valve-seat in the casing 4 and the stem 5 to extend through the end of the casing 4, as shown. A spiral spring 6, bearing at one end against the valve 5 and at its other end against a pin 6 in the open end of the casing 4, acts to hold-the valve 5 closed and prevent the entrance of water through the opening 4 in the casin g 4 into the as shown.

'cuspidor; In connection with the valve 5,

-over and closes the outlet or discharge-opening a in the cuspidorand an intermediate connection consisting of a pivoted lever or arm '8. The plug 7 preferably consists of a disk d, of leather or rubber, secured between two metal plates or disks 6 and f, as shown. A bolt 9 extends loosely through a central opening in the plug 7 and through a hole in the free end of the lever or arm 8, with its head 9 resting on the upper surface of said lever, The nut 9 on the bolt 9 may be turned on or off to adjust the length of the bolt between the head 9 and the nut 9", as desired. The lever or arm 8 is pivoted at 8' between two ears or projections g on the under side of the valve-casing 4 and has an integral upwardly-extending projection 8, extending in front of and adapted to engage the projecting end of the valve-stem 5", as shown. A yoke or fork piece 10 straddles the valvecasing 4 and is pivoted at its lower forked end to the end of the lever 8, which projects beyond the pivotal support of said lever, as shown.

' An operating removable key or tool 11 (shown by brokenlines, Fig. 2) is used to open the valve 5 and will allow the flow of water into the cuspidor without raising the plug 7 to discharge the contents and will also open the valve and raise the plug 7 to discharge the contents of the cuspidor. The key 11 extends through an opening it in the top 3 and engages the upper end of the fork-piece 10 to operate the lever or arm 8 and open the valve 5 to allow the inflow of water and also raise the plug 7 for the discharge of the contents. A slight downward movement of the key 11 will communicate a slight tilting mo tion to the arm 8, as shown by the lower dotted lines in Fig. 2, which, through engagement of the projection 8" on the lever S with the valve stem 5",will partially open the valve 5 to allow the inflow of water through opening 4 without raising the plug 7.' A greater downward movement of the key 11 will open the valve 5 farther and also raise the plug 7,

as shown by the upper broken lines, Fig. 2,

to allow a full flushing of the cuspidor and the discharge of its contents.

The advantages of my improvements will be readily appreciated by those skilled in the art. I provide for an inflow of Water without discharging the Water or contents already in the cuspidor and also for a simultaneous flushing and discharge.

It will be understood that the details of construction of my improvements may be varied, if desired.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A cuspidor, having a discharge-opening, an inlet-opening, a valve at the inlet-opening, with a projecting valve-stem and a pivoted lever, carrying a plug or stopper for the discharge-opening at one end, and having a projection at its other end to engage the valvestem, said lever adapted to be engaged by an operating-key to operate the valve and plug,

substantially as shown and described.

2. A cuspidor, having a discharge-opening, an inlet-opening, a valve at the inlet-opening, with a projecting valve-stem and a pivoted lever havingloosely attached to one end thereof a plug or stopper for the discharge-opening, andaprojection at the other end of said lever to engage the valve-stem, and means for operating said lever to partially open the valve without raising said plug, substantially as shown and described.

3. A cuspidor, havinga discharge-opening, an inlet-opening, a valve at the inlet-openin g, with a projecting valve-stem and a pivoted lever, and a plug or stopper for the dischargeopening attached to said lever, and a projection on said lever to engage the valve-stem, and means for operating said lever to open the valve and raise the plug, substantially as shown and described.

4. A cuspidor, having a discharge-opening, an inlet-opening, a valve at the inlet-openin g, with a projecting valve-stem and a pivoted lever, having a plug for the discharge-opening at one end, and a projection at the other end to engage the valve-stem, and a yoke or fork pivoted on said lever, to be engaged by an operating-key, to operate the valve and plug, substantially as shown and described.
